1994 s50b30 spark plugs

the oem plugs for my car are bosch y5ddc. I would like to go with ngk pkr7a and was wondering whether the ngk can go with the 3.0L.
I know ngk is the oem for the 3.2L but i am getting different results regarding the 3.0L.
If there is anyone here that used ngk with the s50b30, i would love to get his opinion.
Thanks

I've contacted NGK.uk and asked them if the pkr7a can replace the original bosch y5ddc and they said NO due to the fact the pkr7a is a singel ground electrode while the bosch is twine ground design. I've refered them to their web site and they said it's a mistake and thanked me for bringing this issue to their attention.
Just thought it worth clearing this issue.
I'll stick to the bosch for now.
